Author: adrian Date: Fri Sep 18 05:01:05 2015 New Revision: 287948 URL: https://svnweb.freebsd.org/changeset/base/287948 Log: Add an external facing function to manually set the RX A-MPDU parameters for re-ordering. Devices like if_rsu don't pass through action/management frames but do send firmware commands to inform us of things. One of those notifications is the RX A-MPDU negotiated parameters.
